Not even Chronos the Titan of Olympus could do it. Jean however had a daring and almost crazy idea.
He implemented it because there is nothing to lose. And so, he betted. And he betted right
How did Jean do it?
By using the lives and soul of everyone in the Omniverse.
Only that much sacrifice would make it possible to do what he did
In that process, he would be wiped out from existence. If he failed, all that waited him is nothingness. He would never have existed from the beginning.
But if he succeeded, then...a world of possibility would be opened for him.
That price of being wiped out from the existence is not such a bad price especially when the Destroyer was at the last moment of wiping everything out
One must pick the right moment and Jean pick the perfect moment to do what he did. At that one last point of Destruction, there, everything was reborn once again!
